Only working for some torrents (DHT / tracker related?)

Post by PhilipIsPDR »

Hi there,

I'm trying hard to get transmission-daemon working on my home server, which is running the Solaris-derived OpenIndiana OS. I'm running the latest packaged version available for the OS, which is 2.22.

I've got everything up and running, I can log in to the web interface, and I can add torrents - either by dropping them into the watched directory, or by uploading them. Unfortunately, I can only get one torrent to download. This is a torrent of a Ubuntu distribution, and it downloads blindingly fast, which is great - but not a damn thing else does.

I've done all the investigation I know to do, and I can tell you that:
  • port-forwarding looks to be working fine (checked with http://www.canyouseeme.org)
  • transmission is changing "dht-enabled": true, to "dht-enabled": false on startup.
  • the ubuntu tracker that responds is: torrent.ubuntu.com:6969
  • tracker.example.com:80 appears to be the most frequently checked tracker by any of the torrents I upload, and sometimes they only seem to check this tracker. It never responds.
  • many other trackers also do not respond, others (e.g. tracker.hexagon.cc:2710) respond with "Requested download is not authorized for use with this tracker."
All the torrents I've been testing with have been added in the last few days, are active with multiple seeders and leechers, and successfully download from another PC on the same network.

Any ideas, even on what to check next?

Many thanks,
P

We all know who "tracker.example.com" is and the problem is that they changed to using only UDP (as opposed to using HTTP) and Transmission only supports those UDP trackers since version 2.30 (plus version 2.42 has a "Fix error connecting to UDP trackers from big-endian computers", if you use a Sparc processor).

In the case of hexagon the error message tells you it is a private tracker or at least you have to create an account... I just delete those trackers (there are many that don't respond, some don't even exist).

Conclusion: get a newer version.

Well, at least I'm not going nuts! Thanks for the reply - I'll see what I can do to get my hands on / possibly compile (:/) a newer version.

Thanks again,

P
